T all whom it may camera: I

Be it known that I, GEonoE ltrznnsnmnn, a citizen of the United States, residing at Belleville, in the county of St. Clair and State of Illinois, have invented a certain 'new and useful Street-Sweeper, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the.

same, reference being had to the accompanying drawings, forming part of this spec-Hiration.

My invention relates to street sweepers, and has for its object the production of a street sweeper which will be simple in construction and eiieetive in operation, and the brushes of which may be readily adjusted to meet all requircnwnts.

1n the accmn 'ianying drawings, which illustrate one form of street swee mmade in accordance with my invention, ligure. l is a side elevation, Fig. 2 view showing the manner of supporting the rear brush, Fig. 3 is a side elevation, partly in section, looking at the opposite side from Fig. 1, Figs. 4 and 5 are enlarged detailed views showing the manner of so iporting the forward brush, Fig. (3 is a front. 0 ovation and Fig. 7 is a to plan view on a reduced scale.

Like mar s of reference refer to similar parts in the several views of the drawings.

10 is the body orframe of the device, said body or frame being supported on front wheels 11 and rear wheels 12. Adjacent to one of the rearwheels 12 thoreai axle 13 is surrounded by a clutch l-t adapted to be thrown into-and out-of engagement with the adjacent wheel 12 and driving the gear wheel 15 from which the brushes and conveyor are driven, as will he hereinafter described. The clutch 14 is engaged by a bifurcated lever 16 which is rigidly secured to a rock shaft 17. The rock shaft 17 is so iported by brackets 18 on the fran'ie 1t) and ms rigidl secured to its forward end an arm 19, best shown in Fig. (i. livoted to the upper end of this arm l.) is one end of the link 20 to the opposite end of which is iivoted a hand lever 21 situated adjacent to the drivers seat l2,so as to be within reach of the driver, who may thus throw the clutch 14 into or out of engagement with the wheel 12. The gear wheel 15 meshes with a gear wheel .24 mounted upon the end of the shaft 25 carrying the 26. The end of this shaft 25 caris an enlarged sectional rying the wheel 24 is journaled in a plate 17 pivotally mounted upon the axle 13 of the rear wheels. This plate 27 is adapted to be swung with the axle as a pivot by means of an arm 28 which is engaged by a. bell crank 29. This bell crank 29 is pivoted to one end of the link 30, the opposite end of whioh is pivoted to an arm 31 carried by a rock shaft 32. This rock shaft 32 is adapted to be actuated by a hand lever 33 engaging with a suitable toothed rack 34 for retaining it in the desired position. The brush 26 is placed at an angle to the remaining parts of the machine, asbest shown in Fig. 7. In order to allow for its various movements, the shaft 25 is provided near the plate 27 with a universal joint 35 e Embracing the brush 26 and engagin with the shaft 25 is a U-shaped frame or ydke 36 which is attached to the frame 10 by means of a. link 37. This frame 36 is adapted to raise and lower the brush 26 through the medimn of a hand lever 38 adapted to engage with a toothed rack 39. The connection between the hand lever 38 and the frame 36 is best shown in Figs-1 and 5. A bolt 40 is )ivoted to the frame 36 by a pin 41 so as to ailow a rocking movement between the bolt and the frame'in' the direction of the length of the shaft 25. This bolt 40 passes through a block 42 carried on a threaded stud 43 which passes through tlie'hand lever 38 and is engaged h lock nuts 44. The lock nuts 44 are provided so that stud 43 may be allowed to rotate freely in the lever 38. The upper end of the bolt 40 is provided with lock nuts 45 between which and the block 42 is arran ed 'a coil spring 46 so that the brush 26 may nave a certain amount of movement relative to the hand lever 38.

It will be evidentl'rom the above description that the brush 26 may be raised or lowered to bring it into and out of operative po sition by means of the hand lever 38 and at the same time hv means of the hand lever 33 the angle of the brush may be varied to adapt it to the .slant'of the st root on which it operates. the universal joint 35 and tho connection between the frame 36 and the lever 38 MM? l'oi theneeessary movements of the parts.

llngaging with the gear wheel 15 is a gear wheel -18, Fig. l, which is rigidly secured to a shaft to n ma which are mounted two wheels 50 from w rich the conveyor is driven will be hereinafter described. The shaft 49 is These wheels 80 are situated in a hopper 82 provided with a. slanting bottom 83, as shown also provided with a sprocket wheel 51 around which and the sprocket wheel 52 passes a sprocket chain 53. The sprocket wheel 52 is rigidly mounted upon the 54 of the rear brush 55. This shaft mounted on arms 56 which are pivotally mounted on the shaft 49 so that when the brush 55 is raised or lowered the tension of the sprocket chain is not disturbed. In order to protectthe brush 55 and at the same time providemeans for lugs 58 shown in detail in Fig. 2, through which pass the bolts 59 secured to the arms 56 and provided at their upper end with lock nuts 60. Between the lock-nuts 60 and the lug 58 is an upper coil spring 61 and between the lug 58 and the arm 56 is a lower coil spring 62. By this construction, when the hood 57 is raised and lowered, the brush 55 is also raised and lowered and at the same time a certain amount of relative movement is allowed between the brush and hood by the action of the coil springs 61 and 62 so that the brush may adapt itself to the surface upon which it works to a certain extent without disturbing the hood. In order to raise and lower the hood 57, I attach to it a pair of links 63 which are pivoted to arms 64 rigidly attached to theshaft 65.

To this arm 66 is ivoted one end of a link67, the opposite end of which is pivoted to a hand lever engaging with a toothed se ment 69 for holding it in the desired position. The hand lever 69 terminates adjacent to the seat 22 so that the driver may 7 raise and lower the rear brush 55 by manipulating said lever.

The wheels-50 hereinbelore referred to engage with the conveyor 70 passin around and over. suitable supporting w reels 71 mounted in a conveyor trough 72. lower end of the conveyor 70 )asses around a pair of auxiliary supporting wheels 73 mounted between a pair of swinging plates 74 pivoted to the conveyor trough 72 at 75 Fig. 1. These plates 74 are attached to the mod 57 b means of links 76, Fig. 3, so that the said pates 74 are raised and lowered together withthe said hood 57. Between the plates 74 is pivoted a board 77 which terminates adjacent 'to the brush 55 so that the material engaged by said brush is guided by said board on to the conveyor 70, as will be evident from an inspection of Fig. 3. vided for preventing the pivotrd board 77 from coming in contact with the street to be e upper end of the conveyor 70 passe's around auxiliary wheels 80 which are provided with adjusting devices 81 for takmg up any slack in the said conveyor 70.

In order to dampen the street before the brushes operate upon it and thus prevent the scattering of dust by the brushes, I provide a number of nozzles 90 which are contr'olled by a suitable valve 91. ding from this valve 91 is a pipe 92 which 18 connected with a supthe rear end of the his supply tank 93 is provided with a suitable water gage 94 and with an inlot 95 for filling said tank. In addition to the valve 91 for controlling the supply of water to the nozzles, I prefer to supply each lve 96 so that the amount of the discharge of each valve may be individually regulated.

The brushes 26 and 55 may be of any suitable construction. I refer, however, to use brushes made of split amboo set in wooden hoops, as I find this formof'brush to be most effective for my purpose.

In the operation of my device the brushes 26 and 55 are lowered into the pro er osition, the brush 55 being manlpu ate-r by means of the hand lever 68. The brush 26 must not only be lowered but, on account of its projecting to one side of the sweeper, as shown in Fig. 7, it must be adjusted to the slope of the side of the street. This is accomlished by the combined mani ulation of the land levers 33 and 38. The cliitch 14 is now thrown into operative position by means of the hand lever 21, and consequently the brushes 26 and 55 and the conveyor or elevator 70 are operated from the gear wheel 15 through the mechanism hereinbefore de- The brush 26, owing to its angular at one side of the sweeper, throws the dirt toward the center of the machine so that it may be engaged by the brush 55. The action of the brush 55 throws the dirt against. the board 77 by which it is guided to the conveyor 70. Owing to the pivoting of the board 77, it readily passes over any obstruction and again drops into operative po sition. The dirt swept onto the conveyor 70 by the brush 55 is carried, b the conveyer. and finally deposited in t e hopper 82. \Vhcn sutliciont dirt has accumulated in the released by means of the loc lug devices 86 and the dirt allowed to fall out into any suitable receptacle. Owing to the mounting of the brushes, they have a certain amount of movement independent of the adjusting levers and consequently can adjust themselves to any inposition equalitiesin the street which is being swept.

Tank 93 furnishes water to the nozzle 90 so that the street immediately in front of the r with a wheeled frame, of a rotary brush inclincd to said frame, a yoke carryin said brushes may be dampened to a degree sufficient to lay the dust. When the sweeper is not in operation, the brushes 26 and are raised out of contact with the street and at the same time the clutch 14 is released by the hand lever 21.

..Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
